IBM boosts flagship array speeds by 3X with SSD caching

Enhancements to IBM's XIV Storage System include an SSD caching option that can increase system performance by up to three times.

IBM Tuesday unveiled several upgrade options for the flagship grid-based XIV Storage System, including the ability to use solid-state drives (SSDs) as cache to increase performance by up to three times.

IBM's top competitors, such as NetApp and EMC have been offering SSD options for their arrays for a year or more.

IBM today also announced a new Apple iPhone app that lets administrators monitor XIV storage environment through a web-browser interface.

IBM introduced the third generation of the XIV Storage System in July 2011, raising capacity from 256GB to 360GB of DRAM and moving from serial ATA (SATA) drives to higher performance serial SCSI (SAS) drives. The enclosure can hold up to 180 drives.

The new SSD caching option lets users store the most frequently used data on flash, which resides between the DRAM and hard drives.

IBM said it's using commodity 400GB SSD drives to provide up to 6TB of capacity.

Beside the higher performance that comes with serving up highly-accessed data through flash, the SSD cache requires no separate tier to manage, IBM said.

The XIV system automatically distributes the application load across all SSD modules uniformly, putting the aggregate power of all modules at the service of all requests concurrently.

"It comes down to saving customers time and money with extremely efficient, easily managed, virtualized, and high-performing storage systems like XIV Gen3," Doug Balog, vice president and business line executive for IBM Storage Systems, said in a statement.

In addition to the SSD Caching option, IBM added the ability to mirror data between previous versions of XIV and its current XIV Gen3 systems, which it said will ease data migration and allow customers to repurpose their XIV models as disaster recovery backup systems.

Of course, with a price tag that can exceed a million dollars, it would be an expensive backup system.

The app will be available for download at no cost later this month from the Apple Online Store.

In October 2011, IBM released the XIV Mobile Dashboard for the Apple iPad.

IBM today also announced an update to its Linear Tape File System Library Edition. LTFS Library Edition Version 1.2.5 supports Mac OS X and lets users of the operating system create, manage, and optimize video workflows using LTO-5 based tape libraries.
